6.2. Ethyl acetate has a vapor pressure of 118.3 mm Hg at 29.5°C and a normal boiling point of 77.0°C. Estimate the vapor pressure at 45°C using (a) the Antoine equation and constants from Table B.4; (b) the Clausius–Clapeyron equation and the two given data points; and (c) linear interpolation between the two given points. Taking the first estimate to be correct, calculate the percentage error associated with the second and third estimates.
